Everything will flow backwards
What do you mean by a 'parallel delta' circuit -is there such a connection.
the hot and neutral are wired forwards the ground and neutral are wired backwards
In a parallel circuit, the other bulb still works when one fails.
They are wired in series.
A parallel circuit
If it is a properly wired circuit (according to code) in the home, the breaker for that circuit will trip deenergizing the shorted circuit. If it is not properly wired, it could get hot and start a fire and possibly burn down the home.
the paralel
I you wired a light bulb in to the same circuit you have the possibility of over loading the circuit but other than that it would just be brighter.
There are many types of electrical circuits and each one is wired differently. Without knowing the specific circuit that needs to be wired, this question can not be answered.
An ammeter is used to measure the intensity of current flow in a circuit or branch in a circuit. It is wired in series with the circuit being evaluated to accurately measure the current passing through that specific part of the circuit.
if a light bulb is wired it lights if a motor is wired it turns
A series circuit is wired in one direct pathway, meaning the components are connected end-to-end like a chain. In a series circuit, the same current flows through each component, so if one component fails, the entire circuit will be disrupted.
